Ever wonder how they tie up enormous trees for transport? One option is this three-armed model, though you might be distracted by the guy not wearing a hardhat as a giant metal arm spins near his head.
Another model uses an enormous bobbin traveling around a circular track. These can do some pretty big trees.
